HAY-STACKER.

SPECIFICATION forming part of Letters Patent No. 794,825, dated July 18,1905.

Application filed April 21, 1905. Serial No. 256,727.

To all, whom it may concern:

Be it known that I, WARREN E. VVALLER, a citizen of the United States,residing at Charles City, in the county of Floyd and State of Iowa, haveinvented a new and useful Hay- Stacker, of which the following is aspecification.

This invention relates to an improved derrick for hay-stacking and otherpurposes; and it has among its objects to provide a swinging derrick-armwhich shall be readily adjustable to various positions for the purposeof enabling a load to be elevated to various heights.

Other objects are to simplify and to generally improve the constructionand operation of this class of devices.

With these and other ends in View, which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of parts,which will be hereinafter fully described, and particularly pointed outin the claims.

In the accompanying drawings has been illustrated a simple and preferredform of embodiment of the invention, it being, however, understood thatno limitation is necessarily made to the precise structural detailstherein exhibited, but that the right is reserved to any changes,alterations, and modifications to which recourse may be had within thescope of the invention and without departing from the spirit orsacrificing the efficiency of the same.

In said drawings, Figure 1 is a perspective view of a hay-stackingderrick constructed in accordance with the principles of the invention.Fig. 2 is a detail view showing the jointed brace detached. Figs. 3 and1 are sectional detail views taken on the planes indicated by the lines3 3 and 4 4 in Fig. 1.

Corresponding parts in. the several figures are indicated throughout bysimilar characters of reference.

A base-frame is provided, the same including a pair of runners 1 1,connected near the ends by cross-pieces 2 2 and near the middle by arelatively heavy cross-brace 3. Near the four corners of said frame aresupported upwardly-converging braces 4 A, supporting at their upper endsa ring or collar 5, provided with lugs 6, between which the upper endsof the braces 4 are secured by means of bolts 7.

A mast 8 is stepped for rotation in the crossbrace 3, and said mastextends upwardly through the ring or collar 5, in which it is free torotate. A cap 9 at the upper end of the mast serves to pivotally supporta derrickarm 10, which is mounted upon a fulcrumpin 11.

Hingedly connected with one side of the mast is a brace 12, the upperend of which is provided with clip-plates 13, engaging opposite sides ofthe derrick-arm 10. The latter is provided on its under side with aplurality of stop-lugs 14:, against any one of which the upper extremityof the brace 12 may be caused to abut, the adjustment being readilyeifected by simply lifting the outer end of the derrickarm from contactwith the brace and sliding it between the clip-plates or cheek-plates 13until the desired ad ju'stment has been attained.

A link 15 serves to connect the derrick-arm and the brace, so as toprevent liability of accidental displacement of said members withrelation to one another.

The rear or inner end of the derrick-arm is connected with the mast bymeans of a jointed brace 16, the members of which are connected witheach other by means of a hinge 17, and said members having oblique endsabutting upon one another. The upper member 18 of said brace ispivotally connected with the rear end of the derrick-arm. Thelowermember of said brace is pivotally connected with one of a pluralityof lugs 19, secured upon the mast, said lower member being designated20. The upper brace member 18 is provided near its lower end with anauxiliary aperture 21.

The derrick-arm 10 has been shown as provided with guiding means, suchas pulleys 22, for hoisting-tackle of any suitable description, and ahay-fork has been conventionally indicated at 23.

In Fig. 1 of the drawings the folding brace 16 has been shown in fulllines in extended position, and the related parts-via, the derrick-arm10 and the brace 12have likewise been shown in full lines in a positionat which the outer end of the derrick-arm is at its lowest limit. Bydetaching the pivotal pin or bolt 24, which connects the member 20 ofthe brace 16 with one of the lugs 19, the said brace may be folded tothe position indicated in dotted lines, when the lower member 20 of saidbrace will lie in contact with the under side of the upper member 18,the lower end of said upper member being connected with an upper lug 19.In this position the brace 12 has been moved from contact with an outerlug 14, into engagement with an inner lug 1 1, and the derrick-arm willthus be tilted to the position shown in dotted lines, which admits of aload being lifted to a greater elevation, as will be readily understood.

This device, as will be seen, is extremely simple in construction and itWill be found extremely useful for the purpose of building stacks ofvarious dimensions, said device being capable of being easilytransported from one place to another in the field upon the runner-framewhich constitutes the base-frame of the device.

Having thus described the invention, what is claimed is I 1. Abase-frame including runners, converging uprights supported by saidframe, a ring supported by said uprights, a mast stepped for rotation inthe base-frame and extending through said ring, a derrick-beam pivotallysupported at the upper end of the mast and provided with stops upon itsunder side, and a brace hingedly connected with the mast and abuttingupon one of said stops.

2. A mast supported for rotation, a derrickbeam pivotally supported uponthe mast and having downwardly-extending lugs, a brace connectedhingedly with the mast and abutting upon one of said lugs, andcheek-pieces connected with the brace and engaging opposite sides of thederriclrbeam.

3. A mast supported for rotation, a derrickbeam pivotally supported uponthe mast and having downwardly-extending lugs, a brace hingedlyconnected with the mast and abutting upon one of said lugs, and a linkadjustably engaging the derrick-beam and the brace.

4:. Amast supported for rotation, aderrickbeam pivotally supported uponthe mast and having downwardly-extending lugs, a brace hingedlyconnected with the mast and abut ting upon one of said lugs,cheek-pieces connected with the brace and engaging opposite sides of thederrick-beam, anda link adjustably engaging the derrick-beam and thebrace.

5. A mast supported for rotation, a derrickbeam pivotally supported bythe mast, a brace hingedly connected with the mast and adjustablyengaging the derrick-beam, and a link engaging said beam and brace.

6. Amast supported for rotation, aderrickbeam hingedly connected withthe mast and adjustably engaging the beam, and an auxiliary braceconnecting the beam adjustably with the mast, said auxiliary brace beingcomposed of hingedly-connected members.

7. Amast supported for rotation, aderrickbeam pivotally supported uponthe mast, a plurality of lugs upon the latter, and a brace connectedwith one end of the derrick-beam; said brace comprising a plurality ofhingedlyconnected members any one of which may be connected with one ofthe lugs upon the mast.

8. Amast supported for rotation, aderrickbeam pivotally supported uponthe mast and having downwardly-extending stop-lugs, a brace connectedwith the mast and adapted to 'abut upon one of the stop-lugs, aperturedlugs upon the mast, and an auxiliary brace connected with thederrick-beam and comprising a plurality of hingedly-connected membersany one of which may be connected with one of the apertured lugs uponthe mast.

9. The combination with a mast having a pivoted derrick-beam andprovided with a plurality of apertured lugs, of a brace connected withsaid derrick-beam and including a plurality of members having endsobliquely abutting upon one another, and means for connecting any one ofsaid members with one of the apertured lugs upon the mast.

10. In a hoisting apparatus, the combination with a mast and aderrick-beam, of a brace hingedly connected with the mast and adjustablyengaging one end of the derrickbeam, and a foldable collapsible braceadjustably connecting the other end of the derrickbeam with the mast.

In testimony that I claim the foregoing as my own I have hereto afiixedmy signature in the presence of two witnesses.
